Use heat to sooth the earache. Heat can bring quick pain relief. Apply a warm compress over the painful ear. You can make a warm compress from a washcloth dipped in hot water and wrung out, or from a hot water bottle or heat pack purchased at a pharmacy. Do not make it hot enough to scald the skin.
However, too much ear wax can affect your hearing and cause dizziness, pain or itching. For mild to moderate amounts of ear wax buildup, you can clean your ears with a hydrogen peroxide solution at home. Regular cleaning prevents hard wax buildup, which can trap bacteria in the inner ear and causing ear infections.
